Billiard cue

ABSTRACT

A billiard cue includes a shaft section, a bumper, and an assembly of a butt section and an extender segment connected to the butt section and formed as a transparent hollow shaft. The assembly is disposed between and is connected threadedly to the shaft section and the bumper. The extender segment includes a first end wall, a second end wall opposite to the first end wall in a longitudinal direction, and a tubular surrounding wall that extends between and that is connected to the first and second end walls so as to confine a compartment.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention relates to a billiard cue, more particularly to a billiard cue with an extender segment that can enhance the aesthetic appeal of the billiard cue.

[0003] 2. Description of the Related Art

[0004] Referring to FIG. 1, a conventional billiard cue 1 is shown to comprise a shaft section 11 and a butt section 12. The shaft section 11 is formed with a ball-striking tip 111, and a joint end opposite to the tip 111 and formed with an internally threaded bore 112. The butt section 12 has a joint end provided with an externally threaded stub 121 for threadedly engaging the bore 112. Strands are woven around the butt section 12 so as to define a grip portion 122 of the same.

[0005] It is known in the art to connect an extender segment (not shown) to the butt section 12 in cases where the length of the billiard cue has to be lengthened so that a cue ball can be struck in a desired manner. Conventional extender segments are made completely of wood and lack the facility of enhancing the aesthetic appeal of the billiard cue.

SUMMARY OF THE INVENTION

[0006] Therefore, the main object of the present invention is to provide a billiard cue with an extender segment that can enhance the aesthetic appeal of the billiard cue.

[0007] According to the invention, a billiard cue comprises a shaft section, a bumper, and an assembly of a butt section and an extender segment connected to the butt section and formed as a transparent hollow shaft. The assembly is disposed between and is connected threadedly to the shaft section and the bumper.

[0008] Preferably, the extender segment includes a first end wall, a second end wall opposite to the first end wall in a longitudinal direction, and a tubular surrounding wall that extends between and that is connected to the first and second end walls so as to confine a compartment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Referring to FIGS. 2 and 3, the first preferred embodiment of a billiard cue 2 according to the present invention is shown to comprise a shaft section 3, a bumper 6, and an assembly of a butt section 4 and an extender segment 5.

[0017] The shaft section 3 has first and second end portions 31, 32 that are opposite to each other in a longitudinal direction, e.g. the longitudinal axis of the billiard cue. The first end portion 31 is formed with a ball-striking tip 33. The second end portion 32 is formed with a first threaded connector 34. In this embodiment, the first threaded connector 34 is an internally threaded bore.

[0018] The butt section 4 has first and second end portions that are opposite to each other in the longitudinal direction. The first end portion of the butt section 4 has a second threaded connector 41, in the form of an externally threaded steel stub, mounted thereon for threadedly engaging the first threaded connector 34. The second end portion of the butt section 4 is formed with a third threaded connector 42. In this embodiment, the third threaded connector 42 is an internally threaded bore. Strands are woven around the butt section 4 so as to define a grip portion 43 of the same. A plastic ring 44 is mounted on a bottom end face of the second end portion of the butt section 4. The plastic ring 44 presses tightly against ends of the strands on the butt section 4 so that unwinding of the strands from the butt section 4 can be avoided. The extender segment 5 is formed as a transparent hollow shaft and is made of acrylic plastic. The extender segment 5 includes a first end wall formed with a fourth threaded connector 51, a second end wall opposite to the first end wall in the longitudinal direction and formed with a fifth threaded connector 52, and a tubular surrounding wall 53 that extends between and that is connected sealingly to the first and second end walls so as to confine a sealed compartment 54. In this embodiment, the fourth threaded connector 51 is in the form of an externally threaded rod for threadedly engaging the third threaded connector 42 on the butt section 4, whereas the fifth threaded connector 52 is in the form of an internally threaded bore. The sealed compartment 54 may be filled with a liquid 7, such as a mixture of mineral oil and water, as shown in FIG. 3, or may have an article 7′ contained therein, as shown in FIG. 4.

[0019] The bumper 6 is made of a resilient material, such as rubber, and has a sixth threaded connector 61, in the form of an externally threaded steel rod, mounted thereon for threadedly engaging the fifth threaded connector 52 of the extender segment 5.

[0020] During assembly, the shaft section 3 and the extender segment 5 are connected to opposite ends of the butt section 4, and the bumper 6 is connected to the extender segment 5. In this way, when the assembled billiard cue 2 is disposed to stand on a ground surface, the bumper 6 can prevent the extender segment 5 from contacting the ground surface. In addition, the extender segment 5, which is not made of wood, can extend the length of the billiard cue 2.

[0021] Referring once again to FIG. 3, when the sealed compartment 54 is filled with a liquid 7, such as a mixture of mineral oil and water, a lively effect is created therein when the billiard cue 2 is in use. As shown in FIG. 4, the sealed compartment 54 can also be used to contain an article 7′ for conveying information, etc., thereby enhancing the utility and consumer appeal of the billiard cue 2.

[0022]FIG. 5 illustrates the second preferred embodiment of a billiard cue 2′ according to the present invention. Unlike the previous embodiment, the sixth threaded connector 61′ of the bumper 6′ is longer to increase the weight of the billiard cue 2′. The second end wall of the extender segment 5′ is formed with an axial extension 55 which, in turn, is formed with the fifth threaded connector 52′. A protective sleeve 8, which is made of wood, is sleeved fittingly on the extension 55, thereby concealing the threaded engagement between the extender segment 5′ and the bumper 6′.

[0023]FIG. 6 illustrates the third preferred embodiment of a billiard cue 2″ according to the present invention. Unlike the first preferred embodiment, the fourth threaded connector 51″ of the extender segment 5′ is connected to the first threaded connector 34″ of the shaft section 3″, the fifth threaded connector 52″ of the extender segment 5′ is connected to the second threaded connector 411″ of the butt section 4″, and the sixth threaded connector 61″ of the bumper 6″ is connected to the third threaded connector 42″ of the butt section 4″.

[0024] While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
